Datasheet
LED DRIVER IC OF (14~11) X (4~7) SEGMENTS DISPLAY
DESCRIPTION
Fourteen to eleven segment output lines, 4 to 7 grid output lines, one
display memory, control circuit are all incorporated into a single chip
to build a highly reliable peripheral device for a single chip
microcomputer. Serial data is fed to SC16459 via a three-line serial
interface. SC16459‘ s pin assignments and application circuit are
optimized for easy PCB layout and cost saving advantages.
